matic or other resilient tires and has for run its object to provide a knock-down which is divided transversely in sections, which are arranged. to be rigidly secured together, thus facilitating the application and removal of the tires.

Another object is to provide a sectional rim having the abutting ends of each of the sections beveled to afford a support for the sections and allowing connected.

Another object is sections with a longitudinal rib located on the outer periphery for strengthening the sections, and giving an extended support for the rim; certain of the sections having means adapted to en gage the adjacent section for securing 1t thereto. Another object is to provide a sectional rim having a separate means adapted to engage the sections for moving them longitudinally into position to "form the rim.

A still further object is to provide certain improvements in the form, construction and arrangement oi the several elements, where by the above named and other objects may be eliectively attained.

A practical embodiment of my invention is represented in the accompanying drawings in which,

which sections are beveled at & its adjacent section. vided a ong its inner periphery with an extended portion 5 and the section 2 with eX- tended portions 6, 7. Each of the extended portions is shown as the rim, but they may be termed of separate pieces secured to the rim by any well known and approved means. These extended portions are also offset from the body of the rim and serve to strengthen the joint between the adjacent sections, as well as, space the rim from the "telly of the wheel (not shown); Each of the extended portions is provided with holes 8 arranged to'receive pins 9 carried by the adjacent sections to lock the sections against longitudi-.

nal displacement. In addition to this looking means, lugs 10 are formed'on the sections so as to be engaged by the end of the extended portions. To secure the sections in interlocked engagement, l provide a screw 11' engaging a hole 12 in the extended portions and threaded into the body of the rim section immediatel beneath, as shown in Figsr8, 4: 5, 9 and 11. To assemble the sections in position, the section 1 may be interlocked withthe section 3 and the extended portion 5 secured to the section 1 by its screw of the line VHF-VH1 The section 3 is pro-- being formed integral I 11; the section 2 maynow be secured to the section 3 bythe extended-portion 7 being screwed thereto.

When the sections are interlocked in the manner above described, the end of the section 2 carrying the extended portion 6 will overlap the section 1 and it will be necessary to expand these sections in order to gett-he extended portion 6 to engage its pins 9. The expanding of the ends of the sections 1 and 2 is accomplished by means of a tool 13 hav ing a stud 14 and a cam 15 provided with a lip 16. The stud 14 is arranged to enter either of the holes 17 in the rim section 1, and the cam 15 adapted to engage the extended portion 6. Thus it will be seen that as the tool is oscillated on its stud 14, the cam 15 will engage the extended portion 6 and force it rearwardly until it springs back of the lug 10, which will hold it until the screw 11 is inserted. The lip 16 on the cam 15 tends to hold the extended portion 6 from slipping from the cam face while being manipulated. The free end of the tool 13 may be fashioned into a screw driver and tire remover 18 as shown in'Figs. 6, 9, and

Each section of the rim is provided with flanges 19 and a longitudinal rib 20 interposed between the flanges along its outer periphery thus serving to stiffen the section throughout its length. Furthermore, the longitudinal rib 20 togetherwith the flanges 19 support the side walls of the tire, form a bed for the head of the tire, and prevent the flanges from cutting the walls of the tire when deflated.

While I have shown and described a rim having. three separable sections, I wish it understood that the rim may be made in any number of sections.

lit is obvious that various changes may be the adjacent section, means on the adjacent section arranged to interlock the extended portion, a lug on the ad acentsect1on, a sec- 0nd means on the adjacent section for en- 7 gagement of a device arranged to coact with the extended portion to expand the meeting ends into interlocking engagement,

and means engaging the extended portion and the adjacent section for securing the rim sections together.

In testimony, that I claim the foregoing as my invention,I have signed my name this 18th day of September, 1919.
